The most important thing to know about your neighbors is what it sounds like when they unlock their gun racks. When you hear that sound, knock the volume control back a couple of clicks.
I just read this entire thread. I had an interest in the QSC and the Crown amps during the last month. I believe one of the posters in this chain pointed them out to me to consider. I did so. What I read in the comparisons is the build quality on the QSC appears to be of a higher standard than on the Crowns. Hence, harder to cause a failure with rugged or intense use as one of the posters here highlights. Both series of amps appear to have very good $/value ratios.
What an interesting discussion. I appreciated being able to read an entire thread without someone throwing mud at someone else.
